Restrictions on the Number of Distributions for Camera The maximum number of distributions for camera is determined by the settings as well as requirements from the client. For JPEG distribution, you can select either "Frame Rate Priority" mode or "Client Number Priority" mode. "Frame Rate Priority" mode distributes JPEG images according to the frame rate requested by the client. The maximum number of distributions is determined based on the highest bit rate within the distribution streams. For "Client Number Priority" mode, if there are requests from multiple clients, JPEG images are distributed in a lower frame rate than that requested to cater to multiple clients. It can accept 20 distribution requests as the maximum number of clients. Ⅵ When Frame Rate Priority Mode is Selected JPEG images are distributed as the frame rate requested by the client. When a distribution request that exceeds the maximum number of distributions is received, this request is denied. ● When only JPEG images are distributed For example, if Client A requests for JPEG at 1 Mbps, while Client B requests for JPEG at 5 Mbps, additional 2 stream (total 4 streams) of distribution are possible for request below 5 Mbps. Maximum number of distributions when only JPEG images are distributed Distribution at maximum bit rate less than 1 Mbps Maximum number of distributions 20 Total maximum bit rate 20 Mbps less than 5 Mbps 4 less than 10 Mbps 2 20 Mbps 20 Mbps Greater than 1 10 Mbps Greater than 20 Mbps ● When both JPEG and H.264 data is distributed When both JPEG and H.264 images are distributed simultaneously, up to two clients for JPEG and three clients for H.264 can be distributed, respectively. However, distribution requests that exceeds a total bit rate of 20 Mbps will be denied. Maximum number of distributions when JPEG and H.264 data is distributed Maximum number of distribution Total maximum bit rate JPEG 2 H.264 3 10 Mbps 10 Mbps ● When distributing only H.264 data The maximum number of distributions is determined by the preset bit rate. When a distribution request that exceeds the maximum number of distributions is received, this request is denied. Maximum number of distributions when H.264 data is only distributed Maximum bit rate per distributions Maximum number of distributions Total maximum bit rate less than 1 Mbps 20 20 Mbps less than 3 Mbps 6 20 Mbps less than 6 Mbps 3 20 Mbps less than 10 Mbps 2 20 Mbps Greater than 1 10 Mbps Greater than 20 Mbps Ⅵ When Client Number Priority Mode is Selected ● When only JPEG images are distributed If the distribution request would be accepted in the frame rate priority mode, distribution works in the same way as frame rate priority mode, where JPEG images are distributed at the frame rate requested by the client. If the distribution request would be denied in the frame rate priority mode, the frame rate is controlled such that the maximum bit rate is as shown in the following table, to accept distribution requests from up to 20 clients. For example, if Clients A and B request for JPEG at 10 Mbps, the frame rate will be reduced such that the distribution bit rate to each client is less than 5 Mbps. Maximum bit rate when only JPEG data is distributed Current number Maximum bit of distributions rate Total maximum bit rate 2 or less 10 Mbps 20 Mbps 3 to 4 5 Mbps 20 Mbps 5 to 20 1 Mbps 20 Mbps ● When both JPEG and H.264 data is distributed The camera operates in Frame Rate Priority Mode. 5
